Introduction

The fan on your device may need to be cleaned or replaced if your device is experiencing overheating, making unusual sounds or no sound at all, or if your device is frequently shutting down due to overheating.

You can attempt to clean your fan or remove any debris before using this guide. If cleaning the fan has not proved beneficial, you can check the status of your fan in the BIOS settings, and additionally running a fan test.

If you have tried troubleshooting and the issue persists, follow this guide to replace the fan in your Dell Latitude 5580 laptop.

Before beginning, ensure your device isn't plugged in and it is completely turned off. Also, disconnect the battery cable from the motherboard.

Orient your laptop so you can access the bottom cover, with the fan vents facing upwards.
Use a Phillips #00 screwdriver to loosen the eight screws securing the bottom cover.
They are captive screws and do not fully come out of the holes. Don't force them or you may damage the screws or holes on the bottom case.
Insert the end of an iFixit opening tool or opening picks into the seam between the bottom and top case to release the clips holding them together.
Slide the opening tool or pick around the edge of the laptop until it is fully separated.
Remove the bottom cover.

Use the point of a spudger to push on alternating sides of the connector to "walk" the JST connector out of its socket.
It may take a lot of alternating before the connector comes out. Be patient, and don't pull on the cables.
If that doesn't work, use a pair of tweezers to firmly grip the sides of the connector and pull straight away from the socket. Hold the tweezers closer to the connector to get a better grip.
If you're having trouble, try rocking the connector side-to-side to loosen it.
Remove the fan from your laptop.
